How can I tell when the iCloud uploading process is done?

I recently upgraded my iCloud account to the 1TB option and started uploading several hundred gigabytes of files related to my photography and film production business. I can see the cloud icon next to a seemingly random number of files indicating they have not yet been uploaded (hovering over the icon shows "waiting").

My questions are:

Is there a way to get an overview of the entire uploading progress within iCloud?
How can I tell when the uploading process has been completed?
